Discoveries and invention of devices are always welcome till we, humans, find a way to abuse its benefits and be adversely affected by it. This was the case when Wilhelm Roentgen discovered x-rayand within five years, the British Army was using a mobile x-ray unit to locate bullets and shrapnel in wounded soldiers in the Sudan.

TV is such a powerfulmachine that people cannot get away from it – it is addictive.

Apart from the physiological effects, TV also causes psychological effects. One is a result of being exposed to violence. After seeingso many violent scenes on TV, people start considering violent actions normal and they lose their sensitivity to their environment.
